The Globalization of Cultural Eutrophication in the Coastal Ocean: Causes and Consequences

Frontiers in Marine Science, Год журнала: 2020, Номер 7

Coastal eutrophication caused by anthropogenic nutrient inputs is one of the greatest threats to health coastal estuarine and marine ecosystems worldwide. To better understand manage this threat, we compared six contrasting that are subjected a range riverine freshwater (buoyancy) nutrients address (i) impacts on ecosystem services; (ii) how traits minimize or amplify these impacts; (iii) synergies among pressures (nutrient enrichment, over fishing, development, climate-driven in particular); (iv) management ecosystems. Globally, ~ 24% N released watersheds estimated reach Our comparative assessment revealed terms spatial extent habitat degradation, Chesapeake Bay ranks number followed rank order northern Gulf Mexico, Baltic Sea, Great Barrier Reef, East China Sea Adriatic Sea; increases loading are, will continue be, exacerbated with other including development sea surface temperature, acidification rainfall; when defined quantitative ranges primary production, trophic status not useful for relating impacts. While managed reductions point source from sewage treatment plants increasingly successful, controlling diffuse sources remains challenging problem. Thus, it likely severity increase absence effectively enforced, ecosystem-based both nitrogen phosphorus. This requires sustained, integrated research monitoring, as well repeated assessments These must be informed guided ongoing collaborations scientists, politicians, managers public.

Scientists’ Warning to Humanity: Rapid degradation of the world’s large lakes

Journal of Great Lakes Research, Год журнала: 2020, Номер 46(4), С. 686 - 702

Large lakes of the world are habitats for diverse species, including endemic taxa, and valuable resources that provide humanity with many ecosystem services. They also sentinels global local change, recent studies in limnology paleolimnology have demonstrated disturbing evidence their collective degradation terms depletion (water food), rapid warming loss ice, destruction ecosystems, accelerating pollution. particularly exposed to anthropogenic climatic stressors. The Second Warning Humanity provides a framework assess dangers now threatening world's large lake ecosystems evaluate pathways sustainable development more respectful ongoing provision Here we review current emerging threats world, iconic examples management failures successes, from which identify priorities approaches future conservation efforts. underscores extent resource degradation, is result cumulative perturbation through time by long-term human impacts combined other Decades resulted major challenges restoration legacy ecological economic costs generations. will require intense efforts warmer, increasingly populated achieve sustainable, high-quality waters.

Environmental effects of stratospheric ozone depletion, UV radiation, and interactions with climate change: UNEP Environmental Effects Assessment Panel, Update 2020

Photochemical & Photobiological Sciences, Год журнала: 2021, Номер 20(1), С. 1 - 67

Опубликована: Янв. 1, 2021

Abstract This assessment by the Environmental Effects Assessment Panel (EEAP) of United Nations Environment Programme (UNEP) provides latest scientific update since our most recent comprehensive (Photochemical and Photobiological Sciences, 2019, 18, 595–828). The interactive effects between stratospheric ozone layer, solar ultraviolet (UV) radiation, climate change are presented within framework Montreal Protocol Sustainable Development Goals. We address how these global environmental changes affect atmosphere air quality; human health; terrestrial aquatic ecosystems; biogeochemical cycles; materials used in outdoor construction, energy technologies, fabrics. In many cases, there is a growing influence from seasonality extreme events due to change. Additionally, we assess transmission severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which responsible for COVID-19 pandemic, context linkages with UV radiation Protocol.

Geological evolution of offshore pollution and its long-term potential impacts on marine ecosystems

Geoscience Frontiers, Год журнала: 2022, Номер 13(5), С. 101427 - 101427

Populations and metropolitan centers are accumulated in coastal areas around the world. In view of fact that they geographically adjacent to coasts intense anthropogenic activities, increasing global offshore pollution has been an important worldwide concern over past several decades become a very serious problem needs be addressed urgently. Due pollution, various geological disasters occur high frequency, including intensified erosion salinization soils, frequent collapses landslides seismic activities. Moreover, shows increasingly impacts on topography geomorphology areas, degradation, retreating coastlines estuary delta erosion. Offshore sedimentation processes strongly influenced by pH changes terrestrial discharges, sedimentary dynamics have extremely acute complex due pollution. The seabed hydrodynamic environment determine fate transport pollutants entering regions. Coastal estuaries, port basins lagoons relatively moderate ocean currents winds more likely accumulate pollutants. regions undersea canyons can used as conduits for transporting from continent seabed. It is particularly noteworthy spatial/temporal distribution species, community structures, ecological functions undergone unprecedented recent decades. stable succession development trend marine ecosystems broken. thus identify regulate quantity, composition transportation their behavior ecosystems. particular, crucial actions stabilizing ecosystems, species biodiversity, should implemented enhance anti-interference capabilities. This review provides overview current situation well major trends pollutant transformation sediments, bioaccumulation diffusion. study retrospectively reviews long-term evolution perspective geology, analyses potential risks associated with released research influence based geology undoubtedly needed.
